C5 Installing the External Vertical Powerflue (UVP)
Note: For information regarding an internal install of the UVP, go to section C4 on page 15.
The UVP is designed to have the enclosure containing the fan unit mounted externally; an example is
shown below.
Note: When installing the unit onto a flue liner, ensure the length of flue liner above the roof is the minimum
required length. ENSURE the Ø25mm restriction plate is installed on the inlet.
The cowl surround should be fixed in place as shown.
Mount the UVP kit to the top of a chimney flashing plate or penetrate the roof with an optional flue
liner accessory and fit the UVP kit over the flue liner, sealing the penetration with a decktite or similar
flashing. Ensure the terminal is vertical and rigidly mounted and the flexi flue attached below is fixed to
the terminal spigots using the supplied hose clamps. The flexi flue is held in place by drilling 3 holes and
screwing 3 self tapping screws evenly around each hose band clamp (as shown in the picture below).
